The invention relates to a Schiefotübertragungsblatts comprising a flexible substrate comprising a transferable under application of pressure or differentiated heat Sehicht which a synthetic film-forming binder "oily © modifier and a bilderseugenden material contains siw generating an m by means of an alcoholic solution at beschichtet® or uncoated papers duplicating pressure part.

There have been known Sehichtttbertragungsblätter for creating haktographischen printing form images except a synthetic film-forming binder and an imaging material oily modifier contains © n _o for this purpose were partly compatible with the binder modifier, and sometimes incompatible with the binder Modifizierungsnittel for loosening the structure of the film forming binder Such wordenο selected Schiohtübertragungsblätter have the disadvantage that the incompatible ₉ oily modifier tends to diffuse the layer Übertragungemittels due to its incompatibility with the binder of the layer or as an oily layer

to settle on the surface of the Sohioht »This occurred particular at elevated room temperature in appearance and also made one Thenaography-free use of such sheets is difficult. With a shorter storage time and unfavorable influences was there is a risk that the layer may not be properly written off

It is an object of the invention to avoid not only the above disadvantages, but also a layer transfer sheet so that its layer becomes light, especially when applied under pressure, e.g. from a typewriter or a ballpoint pen on the receiving sheet. The best possible contour sharpness must be guaranteed here. Furthermore, the Sohioht be image-wise transferable even through differentiated infrared radiation under the influence of heat.

According to the invention, the object is achieved in that the The layer containing the image-forming substance, the film-forming binder and the oily modifier are natural at the same time or contains synthetic waxes whose melting point is between 40 ° and 110 ° C.

The advantage of using waxes instead of oily modifiers incompatible with the binder is that

that even a much smaller proportion of wax will write off capable fanning of the binder layer guaranteed and none Separation of the waxes can take place by diffusion. By The use of the waxes can also make the sheet good for thermographic Image transmission can be used o

Synthetic plastics, e.g. polyvinyl acetate ₉ ethyl cellulose or polyvinyl chloride or mixtures of these binders in conjunction with natural or synthetic waxes with a melting point of 40 ° to 110 ° C are preferably used as binders.

The binder and waxes used are both used in those for transferring the layer to the support Coming solvents appropriately soluble. All solvents here can be methyl ethyl ketone or toluene or mixtures can be used from both materials »

As natural or synthetic waxes can be used together with the Binder can be used:

Paraffines e.g. normal paraffin, or micro-guard or polyvinyl ' ether waxes «e.g. V wax, or vegetable» animal, mine-. rusty or other synthetic waxes.

You composition of the layer can advantageously be such can be chosen »that the transfer sheet proportions by weight of up to 25 $ for transforming binder, proportions by weight of 0.2 to synthetic or natural waxes and weight percentages of to 40 # oily modifiers and parts by weight of contains up to 65 # image-forming substances or dyes

On the imaging layer of the layer transfer sheet is preferably a non-imaging or dye-free protective layer of synthetic or natural waxes, e.g., paraffin, in the same or as a separate one Operation applied.

Can be used as a carrier material for the Sohichtransferblatt In addition to paper, also plastic films, e.g. made of polyester or Polypropylene.
